So sorry.... When I tested the links it was working, the links they shared are only available if you are on the Lenovo network.

I will upload it to another source. Give me 30 minutes.

 

Files are currently being uploaded on the Lenovo file server. Will update the link once the files are up.

 

Links updated, files have been uploaded to the server. Please refer to the post which is Marked as solution

Well, i don't want to spoil the fun but... it seems to me that with the newest drivers JameZ posted, the issue of the driver not deactivating the unused graphicscard has returned... I'm using a secondary display, so i want the ati-card to be active, to drive the displayport. When i start the computer and boot into windows, temperatures are high, and the fan is runnig at about 2700rpm. Then i deactivate the secondary monitor, switch to the intel card, switch back to the ati radeon, and turn the secondary monitor back on. Temperatures immediately drop, and the fan is turning at about 1800rpm...

can't test right now but is your finding supported by powermanager w/h readings? - if so (and a driver installation issue can be ruled out), i hope we don't have to wait another 6 months...

I had the same concern after installing the drivers.  However, I did a standby resume cycle test under battery power several times and the wattage always dropped back down to 10 or so watts under the intel IGP and my battery life seemed normal. I'm pretty confident  the powerdrain after standby issues are a non issue.  Can anyone else confirm my findings?
